itunes not finding my music (i hate itunes)

Need help, i tunes isnt finding any of my music. I store all my music on my external, the path to all my music is My Book/My Music/Artist/Album/..., for some reason the path to all my music has been broken, but i havent changed ANY folder names since i got my external, which was about 9 months ago. Anybody know why itunes would be doing this?
Is there any way i can view the location that itunes thinks my files are?

P.S. I hate itunes, its the worst program ever made, it give me more headaches than viruses, it should die and burn in hell. That will be all for now.
